英文摘要	In this paper, it new channel assignment strategy named compact dynamic channel assignment (CDCA) is proposed. The CDCA differs from other strategies by consistently keeping the system in the utmost optimal state, and thus the scheme allows to determine a call Succeeding or failing by local information instead of that of the whole network. It employs Hopfield neural networks for optimization which avoids the complicated assessment of channel compactness and guarantees optimum Solutions for every assignment. A scheme based on Hopfield neural network is considered before however, unlike others, in this algorithm an energy function is derived in such a way that for a neuron. file more a channel is currently being allocated in other cells, the more excitation the neuron will acquire, so as to guarantee each Cluster using channels as few as possible. Performance measures in terms of the blocking probability, convergence rate and convergence time are obtained to assess the viability of the proposed scheme. Results presented show that the approach significantly reduces stringent requirements of searching space and convergence time. The algorithm is simple and straightforward, hence the efficient algorithm makes the real-time implementation of channel assignment based oil neural network feasibility.
